UPDATED: Now that is an eddy!

Hi Gang,

Below is updated imagery with wind vectors. Notice the Berkeley T in the fog. This is typically a good sign for Berkeley but with todays low inversion it could be iffy.

Also note the eddy induced fog in the Hwy. 92 gap. Typically not a good sign for 3rd. inside due to intermittent SW flow.

On many recent days we have been cursed or blessed by the tiny Golden Gate just west of the Gate. Cursed if you ply the waters of the coast or much of the Peninsula, Blessed it your home waters are in the Central to East Bay.

Today we have a different type of eddy. The Bodega Eddy is about 10X times as large as the Golden Gate Eddy and is well NW of the Golden Gate and just west of Bodega.

The Bodega eddy is caused more by topography interacting with the NNW west of the ocean buoys while the Golden Gate Eddy is caused more by low pressure in the North Bay. They are both much more likely to occur when the ocean winds west of the ocean buoys turns NNW.

But impact of both eddies on the wind is much the same: Southerly winds on the coast, WSW winds in the north tower to TI to near Berkeley corridor. And a mix of SW-W-WNW winds for the Peninsula.

In this blog you can compare the Golden Gate Eddy and the Bodega eddy.

If you are a long time Bay water person you are probably wondering what is going in the last decade with all these eddies and spring and summer heatwaves. I should do a blog about that sometime but it is largely beyond my very limited expertise so it would be more spec. than fact.

I'd like you to share your speculations about the eddies and the w & wsw typical recent years at 3rd. If you're proven right about them, then we can call it fact.

What's up with Coyote? It's been miserable. Candlestick However is always the bright spot. Sure, I might need my New 2016 Goya 130 and a Retro 6.5 but it's better than sitting on the beach. Love the stick!
